An anonymous reader writes: Friday saw this year's first new posts on the Perl Advent Calendar, a geeky tradition first started back in 2000. It describes Santa including Unicode's "Father Christmas" emoji by enabling UTF-8 encoding and then using the appropriate hexadecimal code.

But in another corner of the North Pole, you can also unwrap the Perl 6 Advent Calendar, which this year celebrates the two-year anniversary of the official launch of Perl 6. Its first post follows a Grinch who used the but and does operators in Perl 6, while wrapping methods and subroutines to add extra sneaky features, "and even mutated the language itself to do our bidding."

Perl/Python guru Joel Berger has also started an advent calendar for the Mojolicious web application framework (written in Perl), and there's apparently also an advent calendar coming for the Perl Dancer web application framework.

An anonymous reader writes: Saturday night saw the announcement of an experimental Perl 5 to Java compiler. "This is the first release," posted developer FlÃvio S. Glock -- after 100 weeks of development. "Note that you don't need to compile a Java file. Perlito5 now compiles the Perl code to JVM bytecode in memory and executes it." He describes the compiler as "a work-in-progress" that "provides an impressive coverage of Perl features, but it will not run most existing Perl programs due to platform differences."

kthreadd writes: Version 5.22 of the Perl programming language has just been released. A major new feature in this release is the double diamond operator; like the regular diamond operator it allows you to quickly read through files specified on the command line but does this in a much safer way by not evaluating special characters in the file names. Other new features include hexadecimal floating point numbers, improved variable aliasing and a nicer syntax for repetition in list assignment. Also, historical Perl modules CGI.pm and Module::Build are removed from the core distribution.

An anonymous reader writes Larry Wall has reportedly announced at Fosdem that "Perl 6 Developers will attempt to make a development release of Version 1.0 of Perl 6.0 in time for his 61st Birthday this year and a Version 1.0 release by Christmas 2015." From the article: "There is going to be the inevitable discussions, comments and probably some mileage from detractors to come. However ever were it so, for us in the Perl Community these are quite exciting times. We have two strong languages and a strong community, I think there is a lot that binds us together so here's looking forward to Christmas."

An anonymous reader writes "For many of us our hosting providers are a way to hone our skills as well as run a business. Which provider out there gives the best bang for the buck for a FOSS developer? Virtually everybody provides Perl, PHP, Ruby, MySQL / MariaDB etc. but where can one get easy and cheap access to a stuff like NodeJS and Big Data? Companies such as Pair Networks are great but not quite on the mark with any of their service offerings for somebody looking to test out real world scenarios with these technologies from a hosted stance. Obviously hosting from home is always an option but that has the penalty of administration, backup, DR planning, bigger security footprint etc. and for those of us whose time is balanced between making money and friends / family time that's not very appealing."

An anonymous reader writes "Perl 5.16.0 is now available with plenty of improvements all around. You can view a summary and all the change details here. With Perl on an annual release schedule, and projects like Mojolicious, Dancer, perlbrew, Plack, and Moose continuing to gain in popularity, are we in the middle of a Perl renaissance?"

chromatic writes "Pumpking Jesse Vincent has just released Perl 5.14, the latest stable version of the venerable Perl 5 programming language. The list of changes in Perl 5.14 includes several enhancements, including performance tuning, Unicode improvements, and updates to the core libraries and documentation. Perl 5.16 is on track for a release next April."

neoflexycurrent writes "A federal court has ruled that photos of a woman on Facebook showing her drinking were properly used as evidence in a child custody case. She had argued she was identified without permission. But the court rejected that argument. In reaching that decision, the court made the interesting observation that: '[t]here is nothing within the law that requires [one's] permission when someone takes a picture and posts it on a Facebook page. There is nothing that requires [one's] permission when she [is] "tagged" or identified as a person in those pictures.'"

First up, reader martinjlogan sends along a tutorial for setting up a workable Erlang/OTP development environment on a Mac. Next, reader acid06 notes news of Perl 5.12, including what may be the first delivered fix for the Y2K38 bug. (Hit the Read More link below for some details on Perl's new release strategy.) "After two years of development, the new major version of Perl is now available. Notable new features are: better Unicode support, proper support for time after the Y2038 barrier, new APIs to allow developers to extend Perl with 'pluggable' keywords and syntax, warnings for deprecated features and more. From the linked post: You can get it from the CPAN right now or wait for a platform-specific release (such as Strawberry Perl for Windows)." Finally, from reader snydeq: "InfoWorld's Martin Heller provides an in-depth review of Visual Studio 2010 and finds Microsoft taking several large steps away from its legacy IDE code. 'Visual Studio 2010 is a major upgrade in functionality and capability from its predecessor. Developers, architects, and testers will all find areas where the new version makes their jobs easier. Despite the higher pricing for this version, most serious Microsoft-oriented shops will upgrade to Visual Studio 2010 and never look back,' Heller writes. Chief among the improvements are Microsoft's revamping the core editing and designer views to use WPF, its overhaul of IntelliSense and support for test-driven development, and its intelligent support for multiple versions of the .Net Framework."
Re: Perl. This release cycle marks a change to a time-based release process. Beginning with version 5.11.0, we make a new development release of Perl available on the 20th of each month. Each spring, we will release a new stable version of Perl. One month later, we will make a minor update to deal with any issues discovered after the initial ".0" release. Future releases in the stable series will follow quarterly. In contrast to releases of Perl, maintenance releases will contain fixes for issues discovered after the .0 release, but will not include new features or behavior.

at_slashdot writes "The Perl CPAN Testers have been suffering issues accessing their sites, databases and mirrors. According to a posting on the CPAN Testers' blog, the CPAN Testers' server has been being aggressively scanned by '20-30 bots every few seconds' in what they call 'a dedicated denial of service attack'; these bots 'completely ignore the rules specified in robots.txt.'" From the Heise story linked above: "The bots were identified by their IP addresses, including 65.55.207.x, 65.55.107.x and 65.55.106.x, as coming from Microsoft."

An anonymous reader writes "Larry Wall wasn't joking when he said that Perl 6 would be ready by Christmas. Perhaps not this Christmas, but that hasn't stopped a group of people (including head Rakudo developers Patrick Michaud and Jonathan Worthington) from putting together an Advent Calendar, featuring one cool Perl 6 feature every day until Christmas. Topics currently covered include how to get and build Rakudo (the most actively developed and progressed implementation of Perl 6) and the new Metaoperators. For those wondering when Perl 6 will be finished: Rakudo will be having its official 'production release' (dubbed Rakudo Star) April 2010."

jamie points out that Perl 5.11.0 was released yesterday, as well as a schedule for future 5.11.x releases, planned for the 20th of every month. Jesse Vincent encouraged testing of the new (development) version, saying, "If you write software in Perl, it is particularly important that you test your software against development releases. While we strive to maintain source compatibility with prior releases wherever possible, it is always possible that a well-intentioned change can have unexpected consequences. If you spot a change in a development release which breaks your code, it's much more likely that we will be able to fix it before the next stable release. If you only test your code against stable releases of Perl, it may not be possible to undo a backwards-incompatible change which breaks your code."

On Elpeleg writes "The Perl Foundation has announced they are switching their version control systems to git. According to the announcement, Perl 5 migration to git would allow the language development team to take advantage of git's extensive offline and distributed version support. Git is open source and readily available to all Perl developers. Among other advantages, the announcement notes that git simplifies commits, producing fewer administrative overheads for integrating contributions. Git's change analysis tools are also singled out for praise. The transformation from Perforce to git apparently took over a year. Sam Vilain of Catalyst IT 'spent more than a year building custom tools to transform 21 years of Perl history into the first ever unified repository of every single change to Perl.' The git repository incorporates historic snapshot releases and patch sets, which is frankly both cool and historically pleasing. Some of the patch sets were apparently recovered from old hard drives, notching up the geek satisfaction factor even more. Developers can download a copy of the current Perl 5 repository directly from the perl.org site, where the source is hosted."

LostDiver writes "Computerworld Australia caught up recently with Larry Wall of Patch and Perl fame. He talks about the development of Perl as 'scratching an itch,' a release date for Perl 6 (Christmas day, year unknown) and beauty versus practicality. Computerworld also has some more information on the upcoming Perl 6. A while back they interviewed Bjarne Stroustrup of C++ fame as well." jamie pointed out a interesting, related video of a presentation by Clay Shirky from last year's Supernova conference in which he discusses why the Perl community (or any web community) drives progress and innovation.

jamie pointed out an important announcement in the Perl community. Adam Kennedy, known as Alias, developed Strawberry Perl to "make Win32 a truly first class citizen of the Perl platform world." Over the last year, major CPAN modules have used Strawberry Perl to get to releases that work trouble-free on Windows. But the tens of thousands of smaller modules on CPAN are lagging, in many cases because of lack of access to a Windows environment for development and testing. Now Alias has worked with Microsoft's Open Source Software Lab to provide for every CPAN author free access to a centrally-hosted virtual machine environment containing every major version of Windows. "More information (and press releases) will follow, the entire program under which this partnership will be run is so new it's only just been given a name, so some of the organisational details will ironed out as we go. But for now, to all the CPAN authors, all I have to add is... Merry Christmas. P.S. Or your appropriate equivalent religious or non-religious event, if any, occurring during the month of December, etc., etc."

mAriuZ writes "Bob Rogers just released Parrot 0.5.2. This monthly release includes a couple of interesting new features. First, we've bundled Patrick Michaud's Rakudo (thats the implementation of Perl 6 on Parrot) such that you can type make perl6 on Unixy platforms and make perl6.exe on Windows and get a working standalone Perl 6 binary. This is experimental and we hope to iron out some installation and deployment issues by next months release, but it was important to demonstrate our progress. The second new feature is a toolkit for starting your own compiler. Max Mohun built a prototype several months ago, and we've added a stripped-down version for now that builds the skeleton of a compiler for you using the Parrot Compiler Tools. I mentioned the LOLCODE compiler in What the Perl 6 and Parrot Hackers Did on Their Christmas Vacation; this is how Simon and Company were able to get LOLCODE up and running so quickly."

Today we have Part 2 in our exciting 2 part series about the infrastructure that powers Slashdot. Last week Uriah told us all about the hardware powering the system. This week, Jamie McCarthy picks up the story and tells us about the software... from pound to memcached to mysql and more. Hit that link and read on.

The software side of Slashdot takes over at the point where our load balancers -- described in Friday's hardware story -- hand off your incoming HTTP request to our pound servers.

Pound is a reverse proxy, which means it doesn't service the request itself, it just chooses which web server to hand it off to. We run 6 pounds, one for HTTPS traffic and the other 5 for regular HTTP. (Didn't know we support HTTPS, did ya? It's one of the perks for subscribers: you get to read Slashdot on the same webhead that admins use, which is always going to be responsive even during a crush of traffic -- because if it isn't, Rob's going to breathe down our necks!)

The pounds send traffic to one of the 16 apaches on our 16 webheads -- 15 regular, and the 1 HTTPS. Now, pound itself is so undemanding that we run it side-by-side with the apaches. The HTTPS pound handles SSL itself, handing off a plaintext HTTP request to its machine's apache, so the apache it redirects traffic to doesn't need mod_ssl compiled in. One less headache! Of our other 15 webheads, 5 also run a pound, not to distribute load but just for redundancy.

(Trivia: pound normally adds an X-Forwarded-For header, which Slash::Apache substitutes for the (internal) IP of pound itself. But sometimes if you use a proxy on the internet to do something bad, it will send us an X-Forwarded-For header too, which we use to try to track abuse. So we patched pound to insert a special X-Forward-Pound header, so it doesn't overwrite what may come from an abuser's proxy.)

The other 15 webheads are segregated by type. This segregation is mostly what pound is for. We have 2 webheads for static (.shtml) requests, 4 for the dynamic homepage, 6 for dynamic comment-delivery pages (comments, article, pollBooth.pl), and 3 for all other dynamic scripts (ajax, tags, bookmarks, firehose). We segregate partly so that if there's a performance problem or a DDoS on a specific page, the rest of the site will remain functional. We're constantly changing the code and this sets up "performance firewalls" for when us silly coders decide to write infinite loops.

But we also segregate for efficiency reasons like httpd-level caching, and MaxClients tuning. Our webhead bottleneck is CPU, not RAM. We run MaxClients that might seem absurdly low (5-15 for dynamic webheads, 25 for static) but our philosophy is if we're not turning over requests quickly anyway, something's wrong, and stacking up more requests won't help the CPU chew through them any faster.

All the webheads run the same software, which they mount from a /usr/local exported by a read-only NFS machine. Everyone I've ever met outside of this company gives an involuntary shudder when NFS is mentioned, and yet we haven't had any problems since shortly after it was set up (2002-ish). I attribute this to a combination of our brilliant sysadmins and the fact that we only export read-only. The backend task that writes to /usr/local (to update index.shtml every minute, for example) runs on the NFS server itself.

The apaches are versions 1.3, because there's never been a reason for us to switch to 2.0. We compile in mod_perl, and lingerd to free up RAM during delivery, but the only other nonstandard module we use is mod_auth_useragent to keep unfriendly bots away. Slash does make extensive use of each phase of the request loop (largely so we can send our 403's to out-of-control bots using a minimum of resources, and so your page is fully on its way while we write to the logging DB).

Slash, of course, is the open-source perl code that runs Slashdot. If you're thinking of playing around with it, grab a recent copy from CVS: it's been years since we got around to a tarball release. The various scripts that handle web requests access the database through Slash's SQL API, implemented on top of DBD::mysql (now maintained, incidentally, by one of the original Slash 1.0 coders) and of course DBI.pm. The most interesting parts of this layer might be:

(a) We don't use Apache::DBI. We use connect_cached, but actually our main connection cache is the global objects that hold the connections. Some small chunks of data are so frequently used that we keep them around in those objects.

(b) We almost never use statement handles. We have eleven ways of doing a SELECT and the differences are mostly how we massage the results into the perl data structure they return.

(c) We don't use placeholders. Originally because DBD::mysql didn't take advantage of them, and now because we think any speed increase in a reasonably-optimized web app should be a trivial payoff for non-self-documenting argument order. Discuss!

(d) We built in replication support. A database object requested as a reader picks a random slave to read from for the duration of your HTTP request (or the backend task). We can weight them manually, and we have a task that reweights them automatically. (If we do something stupid and wedge a slave's replication thread, every Slash process, across 17 machines, starts throttling back its connections to that machine within 10 seconds. This was originally written to handle slave DBs getting bogged down by load, but with our new faster DBs, that just never happens, so if a slave falls behind, one of us probably typed something dumb at the mysql> prompt.)

(e) We bolted on memcached support. Why bolted-on? Because back when we first tried memcached, we got a huge performance boost by caching our three big data types (users, stories, comment text) and we're pretty sure additional caching would provide minimal benefit at this point. Memcached's main use is to get and set data objects, and Slash doesn't really bottleneck that way.

Slash 1.0 was written way back in early 2000 with decent support for get and set methods to abstract objects out of a database (getDescriptions, subclassed _wheresql) -- but over the years we've only used them a few times. Most data types that are candidates to be objectified either are processed in large numbers (like tags and comments), in ways that would be difficult to do efficiently by subclassing, or have complicated table structures and pre- and post-processing (like users) that would make any generic objectification code pretty complicated. So most data access is done through get and set methods written custom for each data type, or, just as often, through methods that perform one specific update or select.

Overall, we're pretty happy with the database side of things. Most tables are fairly well normalized, not fully but mostly, and we've found this improves performance in most cases. Even on a fairly large site like Slashdot, with modern hardware and a little thinking ahead, we're able to push code and schema changes live quickly. Thanks to running multiple-master replication, we can keep the site fully live even during blocking queries like ALTER TABLE. After changes go live, we can find performance problem spots and optimize (which usually means caching, caching, caching, and occasionally multi-pass log processing for things like detecting abuse and picking users out of a hat who get mod points).

In fact, I'll go further than "pretty happy." Writing a database-backed web site has changed dramatically over the past seven years. The database used to be the bottleneck: centralized, hard to expand, slow. Now even a cheap DB server can run a pretty big site if you code defensively, and thanks to Moore's Law, memcached, and improvements in open-source database software, that part of the scaling issue isn't really a problem until you're practically the size of eBay. It's an exciting time to be coding web applications.

unix4reel writes "Internet Cases reports on a new decision from a federal court in Chicago holding that 'the GPL and open-source have nothing to fear from the antitrust laws. The suit was against IBM, Red Hat and Novell, arguing that by distributing Linux for free, they offered products at an unbeatably low price (free), thus discouraging new market entrants and stifling competition. The court took a different view, focusing instead on how the GPL fosters new development."

neoflexycurrent writes "A court in Texas has thrown the book at a defendant accused by the RIAA of file sharing. The court determined that she had intentionally wiped her hard drive clean, so it entered the most severe sanction possible — default judgment against her. The record companies now just have to ask the court how much they want in damages."

dogma01 writes "Parrot the virtual machine for Perl6 and other dynamic languages has released version 0.3.0. If interested you can also help support Parrot development by donating to The Perl Foundation or by getting involved with development."

Simon P. Chappell writes "I don't know about you, but I hardly bother with browser bookmarks any more. I used to have so many bookmarks, back in the early days of Netscape's 4 series, that I would have to regularly trim and edit my bookmark file to prevent my browser from crashing on startup -- that's a lot of bookmarks, folks! Now, I go to my favourite web search engine, enter a couple of appropriate search terms and voila, there's my page! Search engines are so ubiquitous that we rarely give much thought to the technology that powers them. Lucene in Action by Otis Gospodnetic and Erik Hatcher , both committers on the Lucene project, goes behind the HTML and takes you on a guided tour of Lucene, one of a generation of powerful Free and Open-Source search engines now available." Read on for the rest of Chappell's review. Lucene in Action author Gospodnetic and Hatcher pages 421 (7 pages of index) publisher Manning rating 9 reviewer Simon P. Chappell ISBN 1932394281 summary Solid introduction to Lucene Who's it for? Lucene is a library and framework, rather than a complete application. It truly is an engine, around which you are expected to build and extend your own application. Like Lucene, the book is targeted at those who are looking for a tool to build their own search facility application rather than just "download and go." The book does include a number of case studies of Lucene usage (including at least one download and go search engine) but those are included to show how to use and adapt Lucene to fit differing environments rather than as ends in themselves. The Structure The book is sensibly divided into two parts. The first part looks at "Core Lucene" functionality, while the second part addresses "Applied Lucene".

Part one has six chapters, covering the central components and inner workings of Lucene. It's here that the book starts with a tutorial introduction, familiarising the reader with the concepts of Lucene as a search engine around which you wrap your own code. The other five chapters move steadily through good search engine fare, with indexing getting the whole of chapter two to itself The discussion of how to retrieve text from the documents being indexed is mentioned here but postponed until chapter seven, where it is dealt with exhaustively. Chapter three covers searching, and especially how Lucene ranks documents.

Chapter four examines analysis. In it's chapter introduction, the book explains that "Analysis, in Lucene, is the process of converting field text into it's most fundamental indexed representation, terms." This process is performed by an analyser, which tokenises text according to it's own built in rules; each analyser will have a different emphasis, some want only dictionary words, others might explicitly include acronyms and sometimes you'll want an analyser that will block stop words (those words in languages that are part of the structure, but that add nothing to the information being conveyed by the text; classic examples of stop words in English include "a", "and" and "the").

Chapter five looks at advanced search techniques; everything from sorting search results, searching on multiple fields to filtering searches. Many free or open source software tools are extensible, and Lucene is no exception. Chapter six addresses creating and using custom components within Lucene, everything from custom sort methods to custom filters.

Part two, the final four chapters, cover Applied Lucene. It is dedicated to practical uses of Lucene and answers the question "So, what can I do with a search engine?" Chapter seven covers ways and means to parse common, non-plain text document formats. The primary formats covered are RTF, XML, PDF, HTML and Microsoft Word. The ability to parse and index these file formats will cover the search engine needs of the majority of Lucene users. Chapter eight looks at a number of Lucene tools and extensions that are available; many of them being free and open source software. Chapter nine covers ports of Lucene. While for many users, Lucene being a Java library is not a problem, some users want its functionality in environments that do not have Java. The chapter looks at ports written in C++, C#, Perl and Python. Lastly, chapter ten takes a thorough look at seven Lucene case studies. Perhaps the "star" case study is the one about Nutch, a download and go search engine written by Doug Cutting , the original author of Lucene.

There are three appendices. The first offers installation advice for Lucene; a useful addition that those newer to working with Java libraries will surely appreciate. The second appendix has a very well explained description of the Lucene index format. This is the kind of information that can be hard to find, so it is welcome in a book of this sort. The last appendix contains a number of categorised resource references. The number and breadth of the resources provided could provide quite an incredible education in information retrieval theory if the reader was inclined to read them all. What's to Like? There are several things to like about this book. Let's start with the fact that the authors are part of the core development team of Lucene. This gives them both credibility and an excellent understanding of the internal workings of Lucene. Co-author Erik Hatcher is a fantastic writer, having previously been a co-author of the only Ant book worth bothering with, Manning's Java Development with Ant . (Full disclosure: I do know Erik personally.)

The structure of the book is well thought out and each chapter does seem to move your understanding forward when combined with what you learned from the proceeding ones. The division into core and applied Lucene is also helpful. While you'd hope that this was the case, it often isn't; hence I note it as a positive.

I especially appreciate that this book does not fill up page after page with API documentation. The authors appear to have grasped that if you have Internet access to download the software, you might just be able to access the documentation online; rather, they concentrate on the way to use the software. What a concept!

As a part of Manning's "in Action" series, the book has excellent layout and has obviously been thoroughly edited by both technical evaluators and copyeditors. This might seem to be a small thing to some, but a well-edited book stands out clearly from the crowd. What's to consider? If you are looking for a book on using and configuring a download and go style of search engine, this book would be less suitable. While the case study on Nutch is of good length, it would be too short to useful as a configuration guide. Conclusion I enjoyed reading this book. If you have any text searching needs, this book will be more than sufficient equipment to guide you to successful completion. Even, if you are just looking to download a pre-written search engine, then this book will provide a good background to the nature of information retrieval in general and text indexing and searching specifically.

Joseph Brenner writes "Every now and then, a beginning programmer asks if there's any point in learning to program in Perl 5, when Perl 6 is going to change everything soon. There are a number of answers to that: one is to point out that Perl 6 is still years away, another is to point out that it is promised that Perl 5 code will run under Perl 6 without modification (a module that begins with the traditional "package" statement is Perl 5 code; if it begins with the new "class," then it's Perl 6)." Read on for the rest of Brenner's review of Scott Walters' Programming in Perl 6 style using Perl 5, a book which answers that question a whole different way. Perl 6 Now author Scott Walters pages 379 publisher Apress rating 7 reviewer Joseph Brenner ISBN 1590593952 summary Programming in Perl 6 style using Perl 5

Scott Walters here pursues what might be thought of as the third answer: you can learn Perl 6 now and immediately begin writing programs in a "Perl6ish" sort of way, using appropriate CPAN modules that have been used to implement approximations of Perl 6 behavior: Perl6::Variables, Perl6::Export, Perl6::Contexts, autobox, Perl6::Classes, Switch, and so on.

There are many caveats about using these tricks in production code, however, and Scott Walters doesn't shy away from warning you about them (e.g. p.43 "Source filters are dangerous" where he discusses their increased start-up overhead and potential bugginess -- though he doesn't mention my own peeve which is that they're very confusing when you try and use the Perl debugger).

So possibly the book is not really quite so well suited to an actual beginner-- who probably should not be told about "use Switch 'Perl6'", but the device of spending the early stages of the book directed toward a beginning audience makes it a very useful review for people like myself who have been reading the Apocalypses, but don't remember every detail.

And on the other hand, the book includes some prominent early warnings about common gotchas that beginning programmers seem to be prone to -- e.g. using dynamically defined variables instead of just using hashes.

The standards for writing English in the Perl world are pretty high -- the core members of the Perl community have always cared a lot about clear writing, and it's arguably the world's best documented language (critics will no doubt add that it needs to be). Unfortunately, I can't say that Perl 6 Now quite lives up to this standard. This is a book that was written in a hurry, and it shows: hasty sentences and minor organizational problems abound (e.g. one or two items seem to be discussed in the wrong place; there are an awful lot of explicit forward references, and yet there's at least one place where something was used in an example before being discussed a few dozen pages later). But then in Scott Walters defense, this is certainly a book that needed to be written in a hurry, because its subject matter is such a moving target.

And where the book really shines is in its code examples: short, clear and to the point; the author repeatedly shows how something can be done in Perl 5 code and how it's expected to work in Perl 6. These examples are always clearly labeled "Perl 5" or "Perl 6" in the comments, so that the two can't be confused.

The subjects of some of the examples are pretty cool: e.g. he talks about using PDL ("Perl Data Language") to crunch audio data in MOD format, which I was completely unfamiliar with. A *.mod file essentially contains the "sheet music" for multiple parts (really, MIDI) plus sound samples that specify how notes will sound for each voice. This is discussed in Chapter 7, which is also the free sample chapter. I also liked random walking Arizona's highways as an example of Graph navigation (Chapter 8, p 159), and I appreciate the fact that he downplays inheritance in favor of delegation in his discussion of objects (Chapter 14, p. 262).

All in all, this book is a fun read for the Perl fanatic.

(Note: the title Perl 6 Now bears a strong resemblance to an emacs package I've been working on called perlnow.el, but there is no relation.)

An anonymous reader asks: "This summer I have the opportunity to work in a bio research lab creating a web site for data about proteins. Part of my job is to do bioinformatic analysis of the proteins to determine what types of support their are for the preliminary gene predictions. I have been using DNA Stryder (a Mac program) for sequence alignments plus translations from DNA sequences to protein sequences, and I was wondering if any of the Slashdot crowd knew of similar programs for Linux? I have looked into Bioperl , Biopython, EMBOSS, and BioConductor, but they seem to be more oriented towards servers and less towards stand-alone applications. What programs would you suggest, especially those that might be geared more towards biologists rather than computer scientists?"

Andreas(R) asks: "While planning the design of my small programming language, and would appreciate some lessons learned from experienced programmers which have already tried this. I was investigating whether to start from an existing compiler and extend it. The compiler will be based on yacc, or bison. The programming language will be interpreted, object oriented and have higher order programming. Perl 1 seems like a decent starting point, as it's yacc based, and 5000 lines of code. Later versions of Perl are too large to get a good understanding of the whole program in a short period of time. Perl also has the right license (GPL). Is Python out of the question for such a project, since it's not GPL? What other small languages can be used instead? How do I go about designing a small programming language in practice, using what I already know about compiler theory?"

(Read on for a list of changes since the last release, as well as a number of useful links.) Pan T. Hose continues "The most important changes since the previous version 0.1.0 (code-named 'Leaping Kakapo' and released in February) are:

• Python support: Parrot runs 4/7 of the pie-thon test suite

• Improved PIR syntax for method calls and <op>= assignment
• Dynamic loading reworked including a "make install" target
• MMD - multi method dispatch for binary vtable methods
• Library improvement and cleanup
• BigInt, Complex, *Array, Slice, Enumerate, None PMC classes

Slashback tonight brings you updates and corrections from recent and ongoing stories, including (this time around) non-silver silver paste, the return of the Orkut, Mike Rowe and his not-so-epic battle with Microsoft (one last time, I hope), the future of Zip for Microsoft Windows, and more. Read on below for the details.

Funny name, well-executed idea. YourMother writes "After almost 4 days of being offline, the social network Orkut is back online. The Orkut development team has been working nonstop since bringing it down on Sunday afternoon and quite a few new security features have been implemented to protect users information. Within the first 48 hours it was up, it gained almost 100,000 users, growing many times faster than other social networks like Friendster or Tribe. Did Google hit the social network bulls-eye?"

glinden points to a story with some more information about those security holes. "From the article, 'Sources close to Google suggest widespread XSS (cross-site scripting) hacks forced the closure of the service. It isn't clear how much personal data or communication was disclosed.'"

Playmate. Playmate, playmate playmate. An anonymous reader writes "A week after an appeals court ruling revived a Playboy Enterprises Inc. trademark infringement lawsuit against Netscape Communications Inc., the companies have reached a settlement in the case (See a ZDNet report) The terms of the settlement have not been disclosed. This puts an end to a closely watched case in the search engine advertising field. Several other lawsuits over misuse of trademarks in search engine ads are still in place. Google e.g. is embroiled in a lawsuit with Luis Vuitton regarding keyword-based ads in France and asked for a California court's ruling to back its trademark policy for AdWords after facing the threat of a lawsuit from American Blind & Wallpaper Factory Inc."

You have to admire such brave nomenclature. Michiel Frackers writes "Thanks for the link to my site, I got 3 gigabyte of traffic in a few hours! If I would have known, I would have written something in English. I have added an update about the Strangeberry product and its relation to Tivo at the URL you linked to.

I also included a link to my private blog (as www.frackers.com is more about my work in media & technology). Hopefully this clarifies some things for your readers, I did not intend to make this some kind of quest or game at all: it's just that I promised Arthur and his colleagues not to disclose what they are exactly doing, as you will understand."

And Anonymous joe writes with this link to an intriguing bit of Strangeberry speculation at the Register.

Nokia to port Python to Mobiles, not Perl An anonymous reader writes "Nokia was mistaken. In fact, El Reg reports that Python, not Perl, is the preferred language for scripting on its smartphone platforms. The availability of a Python implementation for mobile phones is part of a broader plan, including a JVM-based BASIC interpreter."

However, the Register article linked says that Perl is being considered, it's just that Python is being looked at as the primary language.

I wouldn't trust their pearls, either. Blade Leader writes "OCZ has issued a recall of OCZ Ultra 2 thermal paste after the Overclockers.com article on their lack of silver content. They blame the lack on their supplier, and claim they will be pursuing legal action."

A piece of history (or at least a piece of somethin' ...) Artemis writes "Searching along E-Bay and MikeRoweSoft.com I noticed that Mike Rowe has decided to sell the Microsoft Cease-and-Desist Letters and WIPO book he received on E-Bay. He is selling the WIPO book with the 25-page letter received from Microsoft's lawyers on January 14/2004.This inch-thick book contains copies of web pages, registrations, trade marks, other WIPO cases, emails between me and Microsoft's lawyers and much more. There are 27 annexes filled with information. This package also comes with the 25-page complaint transmittal coversheet that was sent with the inch-thick book."

What's wrong with gunzip, tar? whitefox writes "CNet News is reporting that PKWare & WinZip have settled their differences and will maintain Zip file compatibility for the foreseeable future with each supporting the other's security extensions. In addition, PKWare will include its SecureZip in the code it licenses to other software makers. This is good news in deed for users and developers alike!"

nnorwitz writes "PyCon 2004 is coming to Washington, DC at the end of March. It's a great place to meet lots of smart people and learn new things. Many interesting discussions go far beyond Python into other programming languages and topics. We should find out more about the Pie-thon, the OSAF since Mitch Kapor is the keynote speaker. There may even be a few surprises. The price is only $175, but early bird registration ends soon. It's not too late to submit a presentation either. I hope to see lots of new faces this year! I want to talk to some Perl and Ruby zealots^Wconverts^Wprogrammers. :-)"

Ridgelift writes "Eric S. Raymond is proposing a new logo for Hackerdom. 'The Linux folks have their penguin and the BSDers their demon. Perl's got a camel, FSF fans have their gnu and OSI's got an open-source logo. What we haven't had, historically, is an emblem that represents the entire hacker community of which all these groups are parts. This is a proposal that we adopt one - the glider pattern from the Game of Life.'"

langles writes "Perl 5.8.1 has been released. Read the official announcement, then download it from a CPAN mirror near you. If you've been following the Perl5 Porters List, you'll know this version was very well tested before they released it. However, there may be some modules that will need to be fixed before they will work with this release."
